Abstract

The invention provides a dual power coupling drive assembly adopting a dual-motor rotating speed coupling drive mode, and the dual power coupling drive assembly can meet the power demands of heavy vehicles in the process of running. In the invention, the rotating speed coupling of a planetary gear is used as the power coupling of a first motor 4 and a second motor 8; the first motor 4 and the second motor 8 are arranged at the same side, and the shafts of the first motor 4 and the second motor 8 are parallel to each other, the power output by the first motor 4 passes through a first speed reducer 3, a power input gear 2 and a gear ring external gear 12, the power output by the second motor 8 passes through a second speed reducer 9 and a sun gear 11, then the rotating speed coupling of the two motors are realized by the planetary gear, and a planet carrier 15 outputs power to a driving wheel 16.

Description

technical field [0001] The invention belongs to the technical field of power assembly components, and in particular relates to a dual-motor power coupling drive assembly. Background technique [0002] It is difficult for a single motor to drive a vehicle to meet the needs of low-speed high-torque and high-speed low-torque at the same time. Therefore, in order to meet the power requirements of the vehicle, a gearbox is often added between the motor and the drive wheels. The existence of the gearbox makes the driving motor in the gearbox. The power loss inside is large, and there is a shift power interruption. Contents of the invention [0003] The purpose of the present invention is to provide a coupling drive assembly suitable for dual-motor rotation speeds to overcome the above-mentioned shortcomings in current single-motor-driven vehicles. The transmission path of the braking torque is shortened, which is beneficial to improving the regenerative braking energy recovery ...
